HARRISON H. TAYLOR, OF DETROIT, MICHIGAN, ASSIGNOR TO FRED A.

HUBEL, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 323,753, dated August 4, 1885.I

Application tiled December 8, 1882. (No model.)

To @ZZ whom, it may concern:`

of Michigan, have invented new and useful Improvements in Greasing Machines for Capsule-Molds; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specication.

This invention relates to certain new and useful improvements in machines for greasing or lubricating gelatine capsule-molds; and the machine hereinafter described is specifically designed to lubricate or grease the mold-pins upon which gelatine capsules are formed by dipping by mechanical means.

The invention consists, rst, in the employment of a cylindrical swab, which forms the medium for holding the lubricant; second, in the peculiar manner by which' the pins are evenly coated by frictional contact with the swabs; third, in the mechanical devices for raising and loweringthe mold-plate whenY desired, fourth, in the mechanical devices for throwing the raising and lowering mechanism out of gear and keeping the mold-plate at any desired height; iifth, in the mechanical devices employed for giving to the mold-pins a reciprocating spiral movement; sixth, in the combination of the mechanical devices employed for giving to the mold-pins a reciprocating spiral movement simultaneously, and simultaneously therewith a rotary movement of the swabs in an opposite direction.

The mechanical devices forgiving to the 'mold-pins a movement in a circular orbit around the swabs has been described by me in a machine for cutting off gelatine capsules, for which I have previously applied for Letters Patent, which application is now pending.

Figure 1 is an elevation of my machine with Asome portions thereof shown in vertical section. Fig. 2 is a horizontal section on the line x av in Fig. 1. Fig. 3 is atop plan view of the plate with the crank-wheels journaled therein. Fig. 4t is a bottom plan view of the said plate with the gear-wheels journaled therein.

In the accompanying drawings, which form a part of'this specification, A represents a gelatine mold-plate of the usual construction provided with a series of mold-pins, c.

wheels, each provided on top with a wrist-pin,

D, which enters and carries the table B. E are slides, upon which the wrists D are secured, and whereby the throw of the crank can be varied. F is a lever, pivoted at b, Fig. 3, upon one of the crank -wheels, the wrist-pin D passing through the slot c therein. d is a spring-bolt upon the free end of the lever F, and is adapted to be engaged with any one of the notches e upon the circumference of the cam-wheel. G are vertical shafts, to the upper ends of which the cam-wheels are secure-d, and by means of which they are held in place upon the platey M. To the lower ends of these shafts are secured the gear-wheels II, meshing with a like gear-wheel, I, Fig. 4, centrally secured between the gear-wheels H. The gear-wheel I is secured upon a shaft, f,the upper part of" which forms the means of attaching it to the plate-M, while its lower part is provided with a screw-thread, J, which engages in a nut, K.

spending` socket, L, in the bed-plate N, resting upon its rounding end upon the steel plate-h. g is a notch in the nut k, andi a latch adapted to engage therein. Vertically rising from the bed-plate N are the two posts" O, which serve as guides for the plate M, and have secured upon their upper ends the plates P and R, between which are interposed the rollers K. S is a vertical shaft, held in its vertical position by ears Zupon the rear edges of the plates P and M, and supported upon the latter by a collar, m. To the lower end of this shaft is secured a pinion, T,- Fig. 4L, which meshes with one of the gears H, and to the upper end of it is secured the ordinary crank-haudle V. u are a series of shafts lThe nut K is cylindrical and ts in a correjournaled vertically throughthe plates R and B is a swabs Z, which are adjustably secured therein by means of the set-screws o. The swabs Z are made in cylindrical shape,of some soft elastic and porous material-such as felt, for example-adapted to receive and hold in its pores a quantity of grease. These swabs are securely attached to the shanks 1', which may be more or less elastic.

The operation of the machine, with theparts in the position shown in Fig. l, is as follows: By turning the crank-handle one way the shaft S, by means ofthe pinion Y, will impart arotary motion to all the swabs Z, and by means of its lower pinion, T, it will impart, through the medium of the gear-wheels H and crank wheels C, a crank-motion to the plate B and inoldplate A, giving to the mold-pinsa movenient in a circular orbit. Simultaneously with this movement the screw J will also be rotated,

and as the nut l.: is held iixed by the latch t' the screw .l will raise the' plate M, with all the parts supported upon it, carrying the moldpins a up between the swabs Z and in a spiral. path around the same; and if the throw of the cranks D is now properly adjusted, by means of the lever F, the pins c and swabs Z can be made to rub upon each other, which, when the swabs are. properly greased, will leave a slight and even coating of grease upon these cylindrical parts ofthe pins which come in contact with the swabs. If the motion of the crankhandle is reversed, the plate M will be carried down with the pins, describing a descending spiral path, and the swabs Z revolving around their own axis. The movement of the swabs b and pins is so arranged as to be in directions opposite to each other, so as to prevent any unequal wear upon the swabs and keep their whole surface always evenly saturated.

If the latch z is withdrawn from its engagement with the notch g upon the nut k at any position of the plate M, the raising or lowering movement of the saine is immediately suspended, and the plate M will be kept in the Vsame stationary position. This is practiced when only very small portions of the pins ,have to be greased. The plate M is then su'fliciently raised to bring the desired part of the pins in contact with the swabs; then the latch i is withdrawn, thereby keeping the plate M at itsadJ- usted height, and the mold-plates are then simply slid o'n or off the plate B without disturbing the vertical adjustment of the plate M, and thc pins a will only describe a circular orbit around the swabs.

The spiral paths which the pins describe during the raising and lowering of the moldplate will not be entirely coincident, owing to the lost motion of the parts; but this is only an additional advantage. To get the swabs properly saturated with grease, all there is to pins. The operation is therefore analogous to the operation of cutting the capsules formed on said pins; and the principle of this invention is precisely that of a cutting-machine invented by me, greased swabs being substituted for the cutters of the cuttingmachinc, though I have added certain mechanical details by which the motion of the pins and swabs can be somewhat varied from the motions of the corresponding` parts of the cutting-machine.

Although I have only shown and described mechanism by which the pins can be rotated around the swabs, it is a well-known mechanical equivalent to rotate the swabs around the pins, and this can readily be done by any person skilled in the art by simply setting the shanks 1' which carry the swabs Z eccentrically in the shafts instead of concentrically, just as the cutters shown and described in Reissued Patent No. 6,440, granted to F A. Hubel, October l, 1878, are set. In this case the crank motion which causes rotation is only transferred from the bed-plate B to the swabs Z.

What I claim as my invention is 1. In a machine for greasing capsule moldpins, the combination of the following ele ments, viz: aplate carrying a series of greased swabs at intervals corresponding to the intervals between the mold-pins, a plate carrying a series of mold-pins, a bed adapted to support the mold-plates, and mechanism adapted to move said bed horizontally and vertically, substantially as and in the manner described and shown.
